1 (The nose and mouth make up the first part where air enters your body. 2  The trachea, or windpipe, is the second part and it delivers air to the lungs. 3  Your lungs are the third part where oxygen is absorbed by the blood, which brings it to the rest of the body. 4  Finally, the diaphragm is the fourth part.
Inhalation- Air is breathed in through the nose or mouth. It then travels down the trachea, to the lungs (via the bronchi). When it gets to the alveoli, oxygen is put in the oxygen poor blood and swapped for carbon dioxide. Exhalation- Carbon dioxide is pushed out of your body through the nose or mouth when your diaphragm contracts. At the site of the alveoli, the oxygen goes into the oxygen poor blood that is coming from all over the body. The carbon dioxide is then forced out and breathed out.
